Abstract: To study the cutting ability of the premixed high pressure abrasive water jet on concrete or other materials,the comparative study method was used. Combined with the two cutting methods of mobile cutting and fixed cutting,the comparison experiments of the cutting depth of abrasive and pure water jet on concrete blocks were carried out. The cutting depth comparison experiments of mixed abrasive and water and brown corundum mixed abrasive water jet on concrete block,the comparison experiment of water sand mixed abrasive water jet with different water-sand ratio( mass ratio) on the cutting depth of concrete block were carried out. The influences of analysis of changing pressure , water ,sand ratio and target distance on cutting depth were analyzed. The results showed that the effect of premixed high pressure abrasive hydraulic cutting was more obvious than that of high-pressure pure water cutting. For concrete blocks of different hardness , abrasive hydraulic cutting has obvious advantages; When the target distance reache 1 000 mm , the abrasive hydraulic cutting still had a strong cutting ability.
